+A13-OLinuXino
+
+Intro
+=====
+This default configuration will allow you to start experimenting with the
+buildroot environment for the A13-OLinuXino. With the current configuration
+it will bring-up the board, and allow access through the serial console.
+
+A13-OLinuXino Link:
+https://www.olimex.com/Products/OLinuXino/A13/A13-OLinuXino/open-source-hardware
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make olimex_a13_olinuxino_defconfig
+
+Compile everything and build the rootfs image:
+
+    $ make
+
+Note: you will need access to the internet to download the required
+sources.
+
+Result of the build
+-------------------
+Image ready to be written to your micro SDcard
+
+How to write the SD card
+========================
+
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to a micro
+SD card:
+
+    # dd if=output/images/sdcard.img of=/dev/sdX
+
+Notes:
+  - replace 'sdX' with the actual device with your micro SDcard,
+  - you may need to be root to do that (use 'sudo').
+
+Eject the SD card, insert it in the A13-OLinuXino board, and power it up.

Applied to master, with the following changes:

    [Thomas:
     - use full name in DEVELOPERS file
     - remove parametrization of the post-build.sh script, just hardcode
       the boot.cmd file used as input
     - add missing dosfstools and mtools host packages in defconfig,
       needed because a vfat partition is defined in the genimage.cfg
       file
     - minor tweaks to readme.txt file.]

Could you please check that what I have committed continues to work fine
for you? Thanks a lot!

Best regards,

Thomas
